What struck me when I read Nakazono's text was a number of points at which he strongly emphasized interpretations of various aspects of practice that were diametrically opposed to major tenets of Oomoto-kyo, which he doesn't name as such, but simply describes and labels as wrong views. So I'm starting from the likelihood that the Founder accepted the Oomoto cosmology while Nakazono took a signicantly different view, which he details in INOCHI.

Whether there was any difference in practice (as opposed to interpretation), or whether any difference in interpretation might actually matter is a whole other can of worms that someone opened thousands of years ago which continues to squiggle to this day.....
